在AngularJS中迭代嵌套的JSON对象

Question

{
  "main": [
    {
      "Processing": [
        {
          "Renovation": [
            {
              "Registration": [
                {
                  "Data": "trtl1"
                },
                {
                  "Purpose": [
                    {
                      "Address": "info"
                    },
                    {
                      "Information": "pinfo"
                    }
                  ]
                },
                {
                  "Info": "app.loaninfo"
                },
                {
                  "7.MCC": [
                    {
                      "Info": "info"
                    },
                    {
                      "MHC": "mhc"
                    }
                  ]
                }
              ]
            }
          ]
        },
        {
          "Borrow": [
            {
              "Personal": "bor"
            }
          ]
        }
      ]
    },
    {
      "Audit": [
        {
          "Lookup": [
            {
              "HMDA": "app"
            },
            {
              "Pro": "app1"
            }
          ]
        }
      ]
    }
  ]

}

这是我的JSON，我需要迭代AngularJS / Javascript来获取值。这不是静态数据而是动态数据集，我需要迭代并获得像“Processing”，“Renovation”，“注册”， 来自JSON的“数据”，“目的”，“地址”并将其存储在js对象构建父/子关系中，以在UI屏幕中显示为菜单和子菜单
